he starts talking about the beefs between musicians and goes on to say that with  concerts in europe it was possible to still fight against whats going wrong in DRC as artists could have been used to raise money for good cause or to spread message even without necessarily say stuff which would put their life in danger like most combattants expect
and he then goes on to say there are groups who do that music combattants wants but he never sees more than a bunch a people at their concert but the same people from europe would be throwing thousands of comments on the likes of grace mbizi or carine mokonzi and praising them and then when a popular musician pops up they suddenly re appear like they'll surely do again the day heritier is meant to perform so there is a lot of hypocricy

is he same guy who use to  do "zua nga bien"? and what happened to "zua nga bien"? did it also die out because of the blockade against european concerts?

yes that's him, indeed the concept struggled a lot due to lack of concerts so he went a lot into politics and recently has been showing interest to music again which costed him insults of combattants calling him a traitor
